    摘要： A method for producing electrically conductive zinc oxide comprising calcining zinc oxide under an ambient atmosphere in a vessel at a temperature from about 800.degree. to about 1100.degree. C. in a mixture thereof with aluminum oxide or a precursor thereof convertible into the oxide under the conditions of treatment in an amount of about 0.05 to about 5 moles based on aluminum atom therein in relation to 100 moles of zinc oxide in the presence of solid carbon. A further improvement in the method comprises mixing zinc oxide with aluminum oxide powder of not more than about 20 millimicrons in average particle size in the dry form to provide a feed mixture, and calcining the mixture, to provide a highly conductive form of zinc oxide.

    摘要： A flat cutting tool includes a blade member fixed to a mounting concavity of a base member using a brazing filler metal or an adhesive agent to form a cutting edge on a surface layer side of the blade member. The blade member includes a surface layer which is a high-speed tool steel with a high degree of hardness, a middle layer which is an alloy steel having a lower quench-hardenability than the high-speed tool steel, and a lower layer which is a mild steel having little quench-hardenability, which can be formed by forge welding. The blade member can be quenched and tempered, and the surface layer hardened to a hardness suitable for the cutting tool and fixed to the mounting concavity of the base member.
